The Value of Neatness

In "Order vs. Disorder: Surroundings Matter" Roger Dooley explains how disorder can affect the behavior of people. He cites a study where 13% of the people snatched an envelope with clearly visible a five-Euro note in it from a mailbox. When the mailbox was covered with graffiti, 27% snatched the envelope. Does this mean that a well-organized store would experience less shoplifting? Or that people will buy more stuff from a neat store? The value of neatness is something to think about.
